To all whom it may concern e Be it known that I, FREDERICK W. LIN- AKER,a subject of the King of England, re-v siding at Dubois, in the countyof Clearfield and State of Pennsylvania, have invented certain new anduseful Improvements in Soot-Cleaners, of which the following is aspecification.

This invention relates to certain new and useful improvements in sootcleaners.-

The present invention is particularly designed for use with boilers ofthe Babcock and \Vilcox construction, known in the trade as the B. & WV.boiler, which includes water tubes slightly inclined from the horizontaland arranged in staggered relations, and includes means for diverting ordividing the jets delivered from the cleaning fluid distributing pipe,so that the oblique spaces between the tubes will be traversed by thestreams, as well as affording a protecting means for those portions ofthe upper water tubes that are in direct almement with the dischargeorifices of the cleaning fluid distributing pipes to obviate erosion ofthe water tubes and accordingly prolong the life thereof.

\Vith these general objects in view and others that will appear as thenature of the invention is better understood, the same consists in thenovel construction, combination and arrangement of parts hereinaftermore fully described, illustrated in the accompanying drawings, and thenclaimed.

In the drawings forming a part of this application and in which likedesignating characters refer to corresponding parts throughout theseveral views Figure l is a longitudinal sectional view of a water tubeboiler of the B. & type with the present invention in operative positiontherein. Fig. 2 is a fragmentary detail sectional view showing theinstallation of one form of the soot cleaner in operative positionrelative to the water tubes, an enlarged detail of which is shown inFig. 5.

Figs. 11 and 12 are sectional views of difi'erent forms of distributingpipes, Fig. 11 showing the discharge nozzles or orifices in almement andFig. 12 disclosing the same in staggered relation.

Fig. 13 is a sectional view of another modified form of the invention.

In boilers of the B. & W. type where th tubes are arranged in staggeredrelation, the tubes of the second row being disposed directly beneaththe spaces interveningthe tubes of the first or upper row, difficultyhas been found in employing a mevdlulfiymounted cleaning fluiddistributing pipe with discharge orifices or nozzles discharg ing thecleaning fluid agent in a direct radial path as the fluidwill-necessarily strike the tubes in the second row and after some useof the cleaner, the tubes will become eroded and practically eaten awayand rendered worthless at the points where the cleaning fluid agenttravels in its shortest path to It has heretofore been impractical toclean boiler tubes of this type contact the tubes.

without having the discharge nozzles or orifices of the distributingpipe angularly disposed relative thereto so as to cause the jets I ofcleaning fluid to be directed obliquely through the spaces betweenadjacent tubes. The present invention aims to overcome this difficultyby prolonging the life of the water tube as well as permitting arevolubly mounted cleaning fluid distributing pipe with direct radialnozzles to be used, and

still causing the jets of cleaning fluid agent to travel in obliquepaths in the spaces between adjacent tubes.

Referring more in detail to the accompanying drawings, and particularlyto Fig. 1, there is shown a longitudinal sectional view of a boilerdesignated by the numeral 15, the same being of the B. and IV. type,including steam domes 16 and the water tubes 17 sli htly inclined fromthe horizon tal as is ilustrated. The supply system for the cleaningfluid distributing pipes has a pipe connection 18 with the steam dome,the pipe being connected to the main line 19 supported upon brackets asis illustrated and communicating with any desired number of branch pipes20, three of which are bybolts 3O the cleaning shown in Fig. 1, althoughany number may be employed while suitable controlling de vices andautomatic air relief valves may be employed in the supply system, of anywell known form, in this art.

As shown in Fig 2, the boiler 15 has journaled through one side thereofa revolubly mounted distributing pipe 21 having a sprocket wheel swiveljoint 22 fixed thereto exteriorly of the Wall 15 and operated in theusual manner by the chain 23. The form of distributing pipe 21 shown inFig. 2 has the .discharge orifices or nozzles 24:- arranged in staggeredrelation to provide two alined rows thereof so that the adjacent nozzlesor orifices will project streams toward each other but in differentpaths.

As shown in Fig. 3 there is provided protecting means for the second rowof water tubes 25 in the form of shields supported by said tubes 25 asWell as the tubes 26 in the upper row. Each shield comprises apair ofidentically formed members, the separate members of each shieldincluding a. main plate 27 having, the upper end thereof resting upon anupper tube 26 while the lower end rests upon a. tube 25 in the secondrow. Upstanding lugs 28 are carried by the upper ends of each of themain plates and have curved seats thereon for the reception of thecleaning fluid distributing pipe 21 while a strap or cover 29 isconnected at its ends to the opposite sides of the lugs 28 as to preventaccidental displacement of the distributing pipe 21. Auxiliary plates 31are carried by the main plates 27 and are connected thereto-by ribs 32,the auxiliary plates 31 being adjacently positioned and adapted toengage opposite side of the same water tube 26, disposed between thetubes 26 that support the upper ends of the cotiperating plates 27. Froman inspection of Fig, 3 it will be observed that fluid agent issuingradially from the distributing pipe 21 will first engage the main plate27 and be diverted in an oblique path through the unobstructed spacesbetween the tubes. of shield thecleaning fluid-is prevented from comingin direct contact with the nearest portion of the tube 25 directlypositioned beneath the same as is shown in Fig. 3 and serious damage tothe tubes at this point is prevented.

I have shOWn numerous methods of accomplishing this result, and anotherform. is disclosed in Figs. 5 and 6 wherein the main By this form m ssesshield 34 as is indicated. The shield 34;

is composed of two members of inverted V-shape when assembled on thetube 25, and as shown the adjacent faces of the shield sections 34: arecut-away as at 35 so that the upper ends 36 thereof alone contact. Thus,when the bolts 30 are tightened, the shield sections 34 are caused tobind upon each other and be more securely held in position. With thisarrangement, the cleaning fluid jet delivered from the nozzle 21 willstrike the apex of the inverted V as is evident and be divided into twostreams traveling in oblique paths between the inturned ends33 of theplates 27 andthe shield members 34. With this arrangement, as in Fig. 3,the tubes 25 in the second row are protected from the cutting force ofthe of the tubes 26 in the upper row. The 1 shields are also of slightlydifferent construction, and in this form the means for holding theshields fixed to the water tubes is carried by those portions of theshields engaging the second row of tubes 25. The main plates 27 of theshields terminate at the upper sides of'the water tubes 26 and the lowerends thereof are inwardly directed as at 33 and are connected toV-shaped elements 34 by the ribs 32.. As clearly shown in Fig. 8-, theopposite ends of the V-shaped.

elements 34 are connected by the transverse bolts 40 and upon tighteningthe bolts 10, the same are securely fastened to the tubes 25 while theplates 27 are securely bound to the tubes 26.

The simplest form of construction of the device, and another modifiedform, is shown in'Figs. 9 and 10 and in this instance, the saddle 37 forsupporting the distributing pipe 21 carries a lug for connectionWith'the clamp 39 which is secured about one of the upper tubes 26. Theshieldsfor protecting the tubes in the second row and for dividing thestream delivered from the distributing pipe to cause the same to travelin obaeiasee struction shown in Figs. 7 and 8, but in these Figs. 9 and10, the shields are alone supported by the tubes 25, the same beingformed of companion members 34 surrounding the upper sides of the tubes25 and extending to a point below the horizontal transverse axes thereofas at 41, as is clearly shown in section, while the same are retained inposition upon the tubes 25 by the bolts 40 passing through the uppersidesv thereof. 'The opposed faces of the members 34 in each of Figs. 5,7 and 9 are similarly constructed so that a better binding and retainingaction may be obtained in securing the same upon the tubes.

Still another form of the invention is disclosed in Fig. 13, and asillustrated; the protecting shield is supported on the cleaning fluiddistributing pipe 21, the plates 27 of the shields being constructed ina manner to cooperate with the pipe to permit the suspension of theshields. The clamp used in this form is similar to the clamp shown inFig. 10, the same including a band ortion 39 surrounding an upper tube26 an carrying a seat element 37 forming a journal bearing for thedistributing pipe 21. The lower ends of the plates 27 are diverted andare connected to the shield members 34 by the connectors 32, the shieldbeing substantially of inverted \l-shape as shown in the other figures;but in this form the apexof the shield has an overlapping joint 34 whichobviates the use of fastening bolts 40 and also insures the jointbetween the two shield sections against seepage. of the plates 27 arearranged substantially parallel as is indicated and each upper end isbifurcated to provide a pair of legs 42 that are adapted to straddle thedistributing pipe 21 while a bridge piece 43 connects the upper ends ofthe legs 42 and rests upon the pipe 21 to form a bearing or support forthe plates 27. It will therefore be seen that in the operation of thedevice, the distributing pipe 21 is revolved in the bearings 37 andalthough the shields are supported by the bridge pieces 43 upon the pipe21, relative movement of the shields and pipe is prevented by therelative positions of the different parts of the device.

From the above detailed description of the invention, it is thought thatthe construction and operation thereof will be readily apparent, itbeing noted'that this invention was designed to prevent unnecessarydamage, as erosion, to those portions of the water tubes lying adjacentthe discharge orifices of the distributing pipes, as well as permittinga'distributing pipe having a di-. rect radial discharge orifice to beused and divide or divert the cleaning fluid jets issued radially.therefrom and thereby cause the same to travel in oblique paths. Also,while the nozzles shown inFigs. 3 and 5 are in The upper ends anydesired combination and disposition of the nozzles on the distributingpipes may be provided without departing from the spirit and scope of theinvention as set forth in the following claims.
